Be it known that-I, GEORGE CRoMPro, of.

Worcester, in the 4countyof Vlforcesterand'v State of Massachusetts, have inventedcertain new andinseful Improvements inl Looms; andjl Ido hereby'declare that the following, taken in lconnection vwith the lvdrawings lwhich act `Acompany and form part of thislspecication,

is a description of my .invention'sucient to. enable those skilled in theart to practice it.

My invention hasreference chiefly 'to i'm-i provements in v the ',details of construction lof fancy looms', these iiinprovenients consisting partly in the construction and arra'ngernent of mechanism .for f throwing oi the :loomV by, shipping 'the .belt,'and partly in the manner of mounting thelsh-ipper-forlr',alid'connecting it tothe frame; Q

The drawings represent 'a leoni mechanism embodyingmy improvements.; f Y

Usually the shipper-rod, by which thefshipper-fork is moved, runs through a slotgin a guide and supporting-plate, and dust, waste,

and othermatters soon collect upon the rod at this'slot, and obstruct' its free movement,

` to remedy which-I support the rod, at or near its connection With'the shipper-fork, upon a rocker, as shown.

y The arm 'of the shipper-fork Vis'fconnected to the shipper. lever or handle p by a rod, g, and

bent lever r, and the shipper-fork is made to transfer the drivingfbelt from pulleytopulley', by movement'of this lever or handletowardvv orfrol'nlthe frame, as will be readily understood. Instead of retaining 'the lever in position, and 'the belt upon lthe vfast or loose pulley,

by means of a notch or notches in the gnide piece s, I make use of a swing-latcli'mec'hanism, made and arranged as follows tdenotes a latch, turning' horizontally ion pin, j u. (which is in line with the guide-grooves) and having at its inner end a segment-gear, o, therteeth oi which mesh into the teethiof av l gear-rack, fw, which rack has at its outerend a fork, straddling thev shipper-lever p. (See When the shipper-leveris thrown out in front of the latch and springs, or is thrown down to the end ofthe guide-groove s, the armdrags down the fork and 'thereby moves the;

rack fw, the teeth of which, operating uponv Vthelatcb-segment c, cause the latch to swing "back, as. seen by dotted lines at Fig. 1.v l When the shipper-lever is thrown .backby 7hand-,fthe rack throwsv b'ack .the 1atch, and asy fthe'latch-bar comes inline with the groove,
